APPARATUS FOR MOISTENING AIR.

Specification of Letters Patent.

Patented Nov. 25,1919.

Application filed Jily 2S, 1917. Serial No. 183,323.

To all whom it may concern:

Be it known that I, WILLIAM MILLARD, a subject of .the Kingr of Great Britain, residing at the borough of Manhattan, city, county, and State of New Yorln'have invented certain new and useful Im .rove ir, o which the following is a specification, relverence being had to the accompanying drawings.

This invention relates to improvements in apparatus for impregnating a gas with water vapor and particularly to apparatus by means of which air is made moist and then is incorporated 'in a carbureted mixture that is burned in the working cyl# inder of a gas-engine, such as the gas-engine or motor of an automobile; and an object of this invention is to. provide an. appa.- ratus of the character described which will prove simple in construction, -comparatively cheap in manufacture and efficient in operation and use.' Another object of this invention is to provide an apparatus of the kind just referred to by means of which the results obtained will be uniform in character. Other features of this invention. will be referred to hereinafter.

ln the drawings illustrating the principle of this invention and the best inode new known to me of applying that principle, Figure 1 is a central vertical section through the tank or reservoir of my air-1iioistener; Fig. 2 is a fragmentary section illustrating a modified form of the tank or reservoir; Fig. 3 is a fragmentary section of a second modified form of the tank or reservoir; and Fig. l is a fragmentary elevation showing -a gas-engine cylinder and its mixture,-A

moistening apparatus.

The bod b of the tank or reservoir a, formed o a transparent .glass cylinder that serves as a gage-glass and the lower end of which rests on a rubber gasket c held in the cup-shaped metal bottom rl of the reservoir a. The metal cover or top e of the latter is likewise cup-shaped and receives the upper end of the glass'A body b, between which upper end and the top c, there is inter osed another rubber gasket c. Through iioles f, g, formed in the bottom a3 and the top e, respectively, of the reservoir a, there passes a tube h, the upper otite!` end li off which is threaded exterior-ly and the lower outer end of which is formed with a head h, between which would prevent the watery' from leaking out I of the reservoir a through the perforated cup-shaped top Surrounding the 'cen' trally-disposed tube h and resting on the bottom-d ofthe reservoir a, there is an in vertedcup-shaped (or dshed) member m the cylindrical wall m of which is formed with holes m and .the top"m* of whicliis "formed with a central"v holemi through which passes the tube i. This member m constitutes what may be termed a false bot-v toni; and, lbetween the top mxv of the lat'-` ter and the bottom d of the reservoir a, the tube i is formed with holes h* for the passage of air drawn inwardly through the mouthpiece and the tube h. Into an opening c formed in the top c of the res-A ervoir a, there is screwed one end of a pipe v1 the other end of which is connected with the intake manifold o of the gas-engine cylinder-p (Fig. 4). The pipe nis formed with a coil n intermediate its ends and, 'through this pipe n and the manifold o, the engine-cylinder y; is brought into communication with the reservoir a. As is commonv 'the piston fr moves downward on its sucking stroke, an explosive mixture is drawn through the manifold o' from the carburet-er (j into the cylinder p. time, the airis drawn from the outside Ithrough the mouthpiece k, tube h, holes .ii therein and holes tm, in the false bottom m, the water j in the reservoir a, and the pipe n, into the manifold lo, wherein it becomes mixed with the explosive carbureted mixture flowing therethrough from the carbureter g. By passing the air through the water j 'in the reservoir a, the air is moistened and, in turn, meistens the carbureter mixture with which it mingles and which flows into the cylinder p. By thus meisten- At the saine .50 practically air-tight. The washer i ing the-explosive mixture, the tendency of a deposit of carbon to form on the inside of the'cylinder 7) is counteracted and socalled carbon troubles are in a great measure avoided. It is universally recognized that so-called engine troubles are much less likely to arise in damp Weather and in the cool of the evening than during the heat of a dry day. By the use of the le apparatus hereinbefore described, the atmospheric conditions existinc on a Wet day are, ,to agreat extent, slmullated; andthe engine will be found to work smoothly even in dry weather, when the engine is equipped 1li-with the hereinbefore-descnbed apparatus. v*Should the quantity of water drawn over ywith the air through the pipe n be excessive, the surplus Water Wlll tend to separate from thev air inpassing through the 2o coil a'.

` lIn the structure illustrated in Fig. 2, the false bottom m of Fig. 1 is,4 replaced by a perforated drumlike receptacle s havlng both'a bottom s and a top s and being i raised slightly above the bottom d' of the reservoir a..

In the apparatus shown in Fig.' 3, the tube h* is provided with perforated lateral extensions t-formed with holes t through.I

' which the air passes from the tube h* into the water j and thence to the pipe n. The holes It* in the lower or outlet end of the tube l1, are preferably very small holes,-

commonly called pinli0les,and the'same is -true of the holes m" formed in the false bottom m. The air-passage n ormedin 'the pipe 'n is likewise of small diameter preferably. The false bottom m, the drum s and the perforated lateral extensions t are 40 not essential 'and may be dispensed with, if

so desired. Instead of water j, any suitable solution may be used. The Water or solution may beheld absorbed by any suitable `absorbent material, such as a sponge, layers vcof felt, a mass of cotton waste or the like.'

The washer z" prevents air from Aleaking into the Aair-space b above the Water j;

Aand thel gasket C keeps the joints b between the body-portion 7) and cover or top e gasket c are hence sealing devices. The parts of the reservoir a are held firmly together by the tube I1. and the mouthpiece k, which serve in this connection as abolt and a nut, respectively. The reservoir a is a knockdown structure; for, lby unscrewing the mouthpiece c from the upper end of the tube 71., the body-portion 71, bottom d. cover e and tube h may be readily separated from one another for the purpose of cleaning, rc

newal of worn parts or the making of other" repairs` ln order to replenish the supply of water (or solution) in the container/1. the engine 7) is started and Water poured into the container 1, through the mouthpiece and A 7c. It will be found that the suction produced by the cylinder p causes the reservoir a. to fill rapidly.

I am aware 4that apparatus have heretofore been devised for forcing air through 7e water for the-purpose ot purifying the latten-andan example of such an apparatus is disclosed by United States Patent No. 240813 granted May 3, 1881, to Sidney E. Collins. But the result sought to be attained by the apparatus patented by Collins is entirely foreign to the object of the present invention, which consists in the combina-tion of parts hereinafter claimed.
